“UM SÓ NÃO ESCAPA DE PEGAR EM ARMAS”: AS POPULAÇÕES INDÍGENAS NA GUERRA DOS FARRAPOS (1835-1845)

Este artigo tem como objetivo repensar a história da Guerra dos Farrapos contemplando a presença e a participação indígena nessa rebelião. As populações ameríndias, ao contrário do que se pensava, participaram dos conflitos imperiais, mas seguem como os esquecidos dessa guerra deflagrada em plena fronteira do Império do Brasil.

Nota sôbre o gênero Mononchus de nematódeos predadores

Seven species of the nematode genus Mononchus Bastian, 1865, were found in the State of São Paulo, Brazil. Such are: M. subsimilis Cobb, 1917; M. ibitiensis Carvalho, 1951; M. piracicabae Lordello, 1953; M. risoceiae Carvalho, 1955; M. soutoi Carvalho, 1956; M. coronatus Carvalho, 1956; and M. jairi n. sp. Outside the State, the following species have been found: M. papillatus (Bastian, 1865) Cobb, 1916; M. monhystera Cobb, 1917; M. muscorum (Dujardin, 1845) Cobb, 1916; M. gymnolaimus (Cobb, 1893) Cobb, 1916; M. consimilis Cobb, 1917; M. trichurus Cobb, 1917; M. reversus Cobb, 1917; and M. dentatus Cobb, 1917 (LORDELLO, 1953). This field of investigation has scarcely been touched and additional collections will doubtless add new forms to the number of species known as yet. M. jairi n. sp. most closely resembling species is M. monhystera Cobb, 1917, from which it differs in having: a) labial region more expanded, set off from neck by a broad shallow depression; b) anterior portion of the pharynx-wall rather thinner and directed outward; and, c) smaller dimensions (788.0-924.0: 1,100.0 micros).

Temporal and spatial variation of rocky shores intertidal benthic communities in Southeast Brazil

The relationships between environmental factors and temporal and spatial variations of benthic communities of three rocky shores of the state of Espírito Santo, Southeast Brazil, were studied. Sampling was conducted every three months, from August 2006 to May 2007, using intersection points. Chthamalus bisinuatus (Pilsbry, 1916) (Crustacea) and Brachidontes spp. (Mollusca) were the most abundant taxa, occupying the upper level of the intertidal zone of the rocky shore. The species richness was higher at the lower levels. The invasive species Isognomon bicolor (C. B. Adams, 1845) (Mollusca) occurred at low densities in the studied areas. The clustering analysis dendrogram indicated a separation of communities based on exposed and sheltered areas. According to the variance analyses, the communities were significantly different among the studied areas and seasons. The extent of wave exposure and shore slope influenced the species variability. The Setibão site showed the highest diversity and richness, most likely due to greater wave exposure. The communities showed greater variation in the lower levels where environmental conditions were less severe, relative to the other levels.

Contribuição para o estudo da morfologia de Myrmeleon januarius (Navas, 1916): (Neuroptera, Mymeleonidae)

The author redescrlbes M. januarius (Navas), reared in laboratory, studying also the larvae. One species of Bombylidae belonging to a genus near Diplocampta emerged from two cocoons of the Neuroptera.

Revisão do gênero Seuratia Skrjabin, 1916 e redescrição da espécie Seuratia Shipleyi (Stossich, 1900) Skrjabin, 1916 (Nematoda, Spiruroidea)

Durante a terceira excursão realizada pela Seção de Helmintologia do Instituto Oswaldo Cruz, à localidade de Arraial do Cabo, em Cabo Frio, Estado do Rio de Janeiro, em junho de 1963, tivemos a oportunidade de encontrar ao amanhecer do dia 22 um exemplar fêmea de Diomodea melanophris Temm. (Albatroz), pousado no chão, nas proximidades da praia, provàvelmente levado para lá pela forte ventania que ocorrera durante a noite. Ao necropsiarmos essa ave encontramos, localizados mo estômago, alguns nematódeos dos quais um macho e quatro fêmeas pertencentes ao gênero Seuratia Skrjabin, 1916 e devido à sua raridade nas costas brasileiras e ao achado dos parasitos, resolvemos efetuar o reestudo dêsses helmintos, descritos por Stossich, e rever o gênero proposto por Skrjabin.
